To cir/ZZ whom, it may concern:

Be it known that I, JGHN J osEPH BERRTGAN, of Orange, Essex county, NewJersey, have invented a new and useful Improvement in Centrifugal Machines, of which the following is a specification.

My invention relates to a machine for effecting by the action of centrifugal force the separation of combined constituents and the delivery of the separated constituents from the machine during its operation. The principle embodied in this machine is as follows: to construct and arrange a receptacle for the combined constituents to be separated' so that when said receptacle is rotated upon an eccentric axis passing through it the material introduced will be thrown by centrifugal force against a portion of the innerperiphery of said receptacle, leaving the remainder of said inner periphery substantially dry, and then causing the solid constituent thus deposited to be conveyed over and upon said dry surface to an outlet. By reason of the conveyance of said solid constituent to and upon said dry surface it is reduced by the apparatus to a more completely dried state than it has hitherto been deemed possible to edect through the action of centrifugal force.

My invention consists, broadly, in a receptacle for combined constituents to be separated constructed to rotate on an eccentric axis passing through it; also, in combination, with such a receptacle, of means for conveying the solid constituent deposited centrifugally on a portion of the interior of said receptacle from its place of deposit to another portion of said interior, where the escapeopening maybe located; also, in said receptacle, provided with escape-openings for liquid and solid, located, respectively, on opposite sides of the eccentric axis of rotation; also, in the means for balancing said receptacle with reference to said axis, Whichmeans may operate automatically; also, in the construction of the apparatus whereby a body of water or other liquid may be employed as such automatic balancing means; also, in the construction 'of the apparatus embodying two vessels disposed one within the other and having al common axis of rot-ation passing through said vessels', the inner vessel being eccentric to and the outer vessel concentric with said axis in a plane at right angles to said axis; also, in the construction and arrangement of the scraping device for conveying the deposited solid constituent to the said dry surface and outlet-opening; also, in the various combinations and instrumentalities more particularly set forth in the claims.

In the accompanying drawings, Figures l and 2 are diagrams intended to illustrate my principle. Fig. 3 is a vertical section of a machine in which said principle is embodied on the line 1 1 of Fig. 4. Fig. 4 is a plan view of said machine. Fig. 5 is an exterior view of the top portion of the machine with the collecting-hood removed. Fig. 6 isa diagram in plan showing by arrows the action'of cen trifugal force within the receptacle 8.

Similar characters of reference indicate like Darts.

The base 2 and standard 3, which support the machine, are preferably cast in one piece with the cup 4. Vithin the cup is the rotary vbowl 5, which is secured upon the hollow shaft G. The shaft 6 passes through a `guide-bracket 7 on the standard 3 and is supported and rotated by means hereinafter to be explained.

In the bowl 5 is eccentrically placed the cylindrical receptacle 8, the outer periphery of said receptacle being tangent to the inner periphery of the bowl. The bowl 5 and receptacle 8 are closed above by a cover 9, having a flange 10, which is internally threaded to engage with a thread formed upon the bowl periphery. A gasket 11 may be inter posed between the cover and bowl to make a tight joint.

In the cover 9 is a central opening to re ceive a ianged plug l2, which supports the inlet-conduit 13. Secured on the underside of the cover by the sorewsllt is aplate 15, in which are formed channels 16, Fig. `et, which unite at 17. The part 1,7 of the plate 15 comes directly below the inlet-conduit 13, so that the material to be treated being introduced into the conduit 13 descends and then passes through the channels 16, whence it is ejected by the centrifugal force due to the rotation of the bowl 5 against the inner periphery of the receptacle 8 and preferably against face of the hub of pulley 40 rests.

that part of said periphery which is farthest from the axis of rotation of said bowl.

In the wall of the receptacle 8 is an opening 18, which communicates through a tapering conduit 19, formed in a plate 20,which extends between the receptacle 8 and the bowl 5, with a smaller opening 2l in the wall of said bowl. The openings 18 and 21 and conduit 19 together form a passage through which the solid constituent of the material under treatment after separation escapes from the machine. Any suitable device may be used for collecting the solid which is ejected in comminuted' condition from the opening 21. For example, and as I here show, a detachable annular hood 22, of sheet metal, consisting of the upper conical por-V tion 23 and the flat inner plate 24, may be employed, the plate 24 resting upon the upper edge of the stationary cup 4, into which cup a ange 25 on said plate enters.

The liquid constituent of the material treated escapes from the receptacle 8 through the short tube 2(5,which extends through the bottom of the bowl 5. Below said bowl is a stationary pan 27, the periphery 28 of which extends about up to the edge of cup 4. Just below the bowl 5 this pan has a horizontal annular partition 29, through the opening in which the tube 26 extends. The liquid escaping through the tube 26 is therefore delivered into the pan 27, whence it iiows through the outlet-pipe 30 into any suitable receptacle. The pipe 3l, shown communieating with cup 4, serves to remove any liquid which may leak or drain into said cup.

is a cylinder pivote-d above in the plate 15 and below in the bottom of receptacle 8. Extending from said cylinder are arms 83, which at their ends carry blades 34. W'hen the cylinder 32 is rotated, these blades engage with the solid material deposited on the inner periphery of the receptacle 8 and carry it to the outlet, as hereinafter described.

At the lower pivot of the cylinder 32 is a gear 35, which engages with a gear 36 on the upper end of the shaft 37. This shaft extends through the hollow bowl-supporting shaft 6 and at its lower end is received in the adjustable threaded step 38. The step 38 in turn is received in the threaded fixed sleeve 39, which may be integrally cast with the standard 3.

The shafts G and 37 are actuated in the following manner: Fast on the shaft (i is a grfooved pulley 40, to which motion is imparted by a belt 41 from any suitable motor. V Fast also on the shaft 37 is a grooved pulley 42, driven by a belt 43 from said motor. The upper face of the hub of pulley 41 is channeled to receive balls, upon which balls the lower The weight of the bowl 5 and its contents is therefore taken upon the ball-bearing between pulleys 40 and 42 and thence communicated to the shaft 37 and its supporting-step. The pulley 42 is larger in diameter than the pulley 40.

Hence if both belts lead from the same drivl ing-pulley the shaft 6, which supports the bowl 5, will be driven at a higher speed than the shaft 37, which actuates the cylinder Furthermore, by reason of the interposed gears 35 and 36, although the shafts 6 and 37 are both rotated in the same direction, the cylinder 32 will be rotated in the direction opposite to that of the bowl 5. Hence the blades 34 will also travel in a direction opposite to that of bowl 5 and at a slower speed than said bowl, and in this way their action upon the solid material upon the inner periphery of receptacle 8 is augmented. The shaft- G extends through a gland 44, which rests upon an annular plate 45, secured to the top of standard 3. Beneath said plate is a packing-ring 46, which is received in a recess 47 and which bears against the exterior of gland 44.

In the wall of receptacle 8 are provided openings 48 and 49. Also through the solid portion of plate 2O and respectively above and below the conduit 19 therein are openings 50. The purpose of the openings 48, 49, and 50 is to establish communication for liquid to flow from receptacle 8 to bowl 5 and in the bowl from one side of plate 2O to the other.

Having now described the construction of the specific machine here exhibited as an embodiment of my principle, I will now explain how said machine operates, referring for con venience :rst to the illustrative diagrams, Figs. 1 and 2.

Fig. 1 shows in plan a circular vessel-such as the bowl 5, for example-rotating on a central axis G and without internal partitions or chambers. If a liquid is placed in such a rotating bowl, it will form through the action of centrifugal force a ring in contact with the inner periphery of the bowl. If a combined liquid and solid be introduced, then the solid (if heavier than the liquid) will form a ring, as a, against the periphery, while the liquid will form a ring b within the ring ct. If the liquid is heavier than the solid, then the liquid will form the outer ring a and the solid the ring l). In Fig. 2 I have placed the receptacle 8 eccentrically within the bowl 5. Assume liquid only, as water, to be introduced into receptacle 8. Then that liquid will flow through the openings at 48 and 49 from the receptacle into the bowl, and, as before, by the action of centrifugal force when the bowl is rotated will form a ring which will extend around the inner periphery of the bowl and be intersected at relatively opposite points, as c d, by the periphery of receptacle 8, or the position of the receptacle 8 in the bowl 5 may be thus defined as follows: that said receptacle is so placed in said bowl that a portion of said receptacle extends into the layer of material formed around and within the bowl periphery by the action of centrifugal force. Now it' the bowl in Fig. 2 be considered for the moment at rest then the liquid will of course meet every part of the immersed periphery of the receptacle 8;

but when the bowl is in rotation and the liquid ring is formed the liquid in the receptacle 8 is withdrawn from all that portion of the inner periphery thereof which is included in the'arc c e d between c and d which lies nearest the axis of rotation and concentrated in that portion of the periphery which is included in the arc c f d between c and d which lies farthest from the axis of rotation. The arc c e d therefore shows the extent of inner surface of the receptacle 8, which by reason of the withdrawal of liquid therefrom becomes a substantially dry surface. Obviously its length measured circumferentially around the receptacle 8 will depend upon the location of the points'c CZ where the ring of liquid intersects the periphery of said receptacle or, in other words, upon the thickness of the ring measured radially to the axis of rotation. Obviously, again, the thickness of the ring will be dependent upon the distance of the liquid-outlet similarly measured from said axis. Thus if said outlet be located at 26 in Fig. l the thickness of the ring will be determined by the distance of the hole from the axis of rotation and will be equal, or substantially so, to the distance of the hole from the innerperimeter of the bowl. If the opening at 26 were moved nearer to the perimeter of the bowl 5, the ring would be thinner, the arc c f d smaller, and the dry surface c e d larger. If the opening at 26 were moved nearer to the center of bowl 5, the ring would be thicker, the arc of d larger, and the dry surface c e cl smaller. With this explanation any one skilled in the art can regulate the perimetrical length of the dry surface in the receptacle 8 as he may deem best. S0, also, hemay accomplish a like result by increasing or diminishing the diameter of the receptacle 8 or by changing the shape or conliguration of said receptacle. So far I have considered for the sake of simplicity in explanation a liquid only as introduced into the receptacle 8 ot' Fig. 2 and forming a ring around the periphery thereof in the manner described. Now assume that after the ap-u paratus has been started with liquid only a fluid mass of combined solid and liquid is introduced into receptacle 8 and preferably directed so that it meets the inner periphery of said receptacle at f, the point of tangency between said receptacle and bowl 5. The solid constituent will at once be thrown against the inner periphery of receptacle 8, as shown at a', but not against the inner periphery of bowl 5 exterior to said receptacle, because it is retained in the latter, the wall thereof forming an efficient barrier. The liquid in the introduced mass may mingle through the openings 48 and 49 with the liquid in the bowl 5 first introduced. Therefore the ring of material formed by the action of centrifugal force is not a continuous ring aof solid with an internal continuous ring b of liquid, as in Fig. 1, but is a ring made up of a part wholly liquid-namely, that part outside of the receptacle 8-and a part which is formed of solid material d and liquid bnamely, that part inside the receptacle 8. This state of affairs being clearly apprehended, I come to the mode of dealing with the two materialssolid andliquid-thussegregated. Inearlier machines the organization has been such as to produce the double continuous ring ab of Fig. l. The solid material in my judgment cannot be got out of an apparatus thus organized Without bringing with it an amount of liquid which by ordinary processes and with the materials for which centrifugal treatment is desirable cannot be expelled except at prohibitory cost. Consider now the new conditions. From the receptacle 8 of Fig. 1 the liquid thrown against the periphery escapes by the opening 26, leaving the solids still adherent. Now conceive a means of carrying that solid from the place of its deposit c f d, Fig. 2, away from the liquid layer to the dry surface c c d, Fig. 2, and then transporting it over that surface before allowing it to escape. not in liquid, but in the presence of the at- The solid is now being revolved mosphere, and thus it is rapidly deprived of moisture.

I have lalready pointed out how the absolute length of the dry surface may be varied. It is also possible in the construction illustrated in Fig. 2 to vary the eective length by suitably placing the orifice at which the dry solid escapes. Thus if the solid is carried over the dry space in the direction CZ e c then if the outlet be placed, say, at g, Very near to c, the solid material will be carried over the entire length of the dry surface before it is permitted to escape. If the opening be placed at e, midway betweend and c, then the material will be carried over half that surface, and so on. Thus the person skilled in the art may establish for himself the desired effective length of dry surface. Inasmuch as the receptacle 8 is by this construction eccentrically placed with reference to its axis of rotation it is of course necessary to balance it. This I may accomplish by disposing a suitable counterbalance on the opposite side of the axis of rotation to that 0n which the receptacle 8 or the greater por. tion thereof is situated. The best counterbalance which I know is a liquid introduced into the space between the receptacle 8 and the bowl 5, because such liquid not only acts by its dead-weight, but also operates as an automatic balance constantly adjusting itself with respect to the amount of material contained in the receptacle 8-that is to say, when by the action of the scrapers the lsolid is removed from the receptacle 8, thus disturbing the normal condition of equilibrium, a small amount of liquid will run in to compensate for this removal, and, conversely, when solid is permitted to accumulate in any way in the receptacle 8 a certain small amount of liquid is forced out of that receptacle and into the space between receptacle IOO IIO

and bowl, and in this way the equilibrium is restored.

The liquid which remains in the space between the receptacle 8 and the bowl` does not practically escape from the apparatus and should notbe confounded with the liquid which comes in as part of the combined constituents to be separated and drawn off in l the manner described through the pipe 26. In

other words, the liquid between the receptacle and bowl is practically permanent in its place as long as the apparatus is in operation and constitutes simply a counterbalancingweight, like, for example, the liquid in the;

trimming-tanks of ships.

Another feature to which I desire to call especial attention is that the receptacle 8 forI gal force due to the rotation of said receptacle on said axis always has a component acting radially outward from that axis or, in other words, around the entire circumferential path of rotation.

`the combined constituents to be separated is i so disposed with reference to its eccentric` ally-placed axis of rotation that the centrifui This will be more clearly understood by referring to Fig. `6, in? which the magnitude of the centrifugal force? acting radially within the receptacle 8 from f the axis A is represented by the arrows B C D E F G.

It will be observed that the effect of the centrifugal force always tends Ato ca use the material to lie in contact with the inner periphery of receptacle 8 and never to move away therefrom.

B, and it decreases in magnitude around to `the arrow E, directly on the opposite side of the axis of rotation. Now the directingchannels 16 in plate l5 are in line with the arrow I3 and project the material against the inner periphery of receptacle S in the direction of that arrow. Consequently after the combined materials meet that inner surface there `is no force tending to throw them away therefrom, and still while the materials are carried around by the Scrapers to and over the part that I have defined as the dry sur- This force reach esits great l est magnitude as represented by the arrow} face the centrifugal force alwa 7s acts to rel tain them against that surface. of the arrow E, where that force would reach its minimum, I prefer to place the conduit 20, so that, as a consequence, at this particular point, by reason of the open conduit 20, the centrifugal force at once assumes the At the place magnitude represented by the arrow B' and of centrifugal force through the channels 1G and is projected against that part of the inner periphery of `the receptacle 8 which is farthest from thc axis of rotation of the bowl 5, and, as has already been described, there will thus be formed a layer of solid immediately adjacent to said periphery at the part aforesaid and a layer of liquid inside the solid layer. The liquid layer will escape through the pipe 26, pass to the pan 27, and out at the pipe 30 into any suitable receptacle. The solid layer as fast as it is formed is removed from the inner periphery of receptacle 8 by the revolving blades 3i and is carried over to the dry surface within the receptacle 8 in the manner already described. This dry sur- `face in the machine here shown extends from either the opening 48 or the opening 4L!) to the escape-opening `18, depending upon the direction of rotation. In this particular machine I place the plate 20, containing the ta pered outlet-conduit, in line l l of Fig. 4, and therefore in the line which passes through the axis of rotation and the point of tangency of the periphery of receptacle S and the periphery of bowl 5, for the sake of the better balance obtained. I therefore use only one-half of the effective dry surface, which I find by actual experiment with this machine to be practically suflicien t. The solid material is therefore ,carried by the blade 34@ over` the dry surface within receptacle 8, and then by .the action of centrifugal force it is ejected through the conduit 19 and opening 2l in the side of the bowl into the collecting-hood 22, .where it accumulates upon the horizontal plate 2t in the angle between that plate and the conical top In order .to remove the collected solid, the hood 22 is lifted from the machine and the solid shaken out. Of course I do .not limit myself, as I havestated, to the use of such a collecting-hood as this, and, in fact, in practice it would be desirable to provide some appropriate means for continuously conveying away the ejected solid.

It will be seen, therefore, that the operation of this machineis continuous-that is to say, it continuously receives the combined solid and liquid and continuously' ejects the solid and liquid in separated state, Even when a hood as here described is employed it will be desirable to substitute immediately another and similar hood when the iirst one is removed after it is filled.
